One thing I haven't mentioned
I've talked about my wife and girlfriend at length, there is another, an ex girlfriend I reconnected about 12 years after breaking up(4 years ago) the wife was attracted to her, the girlfriend was as well, but after about a year, the 3 of us decided that a 4th was too much drama, plus she liked to have unprotected sex with random internet guys, none of us wanted a disease, so no more sexual relationship. Seems simple enough, we all want to remain friends, but she is always making advances, we're all grown ups, all with a strong will of our own, so nothing's going to happen. I just need to know how to make it more clear to her without sounding like an asshole, and hopefully without losing a friendship.
Any ideas? thanks
